以超级用户权限运行脚本

我需要创建一个脚本来修改一些数据，这需要超级用户权限。有没有办法通过 Mac 10 上的 shell 脚本自动执行此过程？

示例脚本：

sed s/Hello/World/g /usr/local/opt/test.xml

要运行此脚本，用户需要超级用户权限，有没有办法在脚本中提供root凭据并执行？

答案1

您可以更改 shell 脚本文件的权限，以自动使其以 root 身份运行。

来自 chmod 手册页：

4000    (the set-user-ID-on-execution bit) Executable files with
        this bit set will run with effective uid set to the uid of
        the file owner.  Directories with the set-user-id bit set
        will force all files and sub-directories created in them to
        be owned by the directory owner and not by the uid of the
        creating process, if the underlying file system supports
        this feature: see chmod(2) and the suiddir option to
        mount(8).

示例命令可能如下所示：

sudo chown root:root file.sh
sudo chmod 4755 file.sh
